I have Kaspersky Internet security and use the ad blocker feature. It is listed in Firefox extensions. All other extensions are disabled. Is Kaspersky strong enough to prevent any invasion?
My Flash Player has been updated automatically.

Is Kaspersky strong enough to prevent any invasion? My Flash Player has been updated automatically.

If you have Flash Player set to update automatically then it should now be at version 21.0.0.213 (except for Google Chrome which has been updated to 21.0.0.216) and you are protected from this particular vulnerability.

You should be able to check this by going to the Control Panel and running the Flash Player applet.

This means that, irrespective of what antivirus product you are using, Flash Player itself isn't vulnerable to the current exploit.

(Note that the Flash Player auto-updater doesn't appear to delete the previous version of Flash Player immediately but - instead - waits until you reboot, i.e. the files (executable and DLL) are flagged in the registry for delete on reboot. The auto-update process should re-direct all calls to the new version of Flash Player but, if you're being really cautious, it's a good idea to reboot to get rid of the old version files completely.)

I have Flash, like all other software, notify me before installing. Nothing more annoying than software suddenly updating in the middle of something.

However, I rarely actually get notified. Usually I find out from WinSecrets or similar. Annoying they don't notify with the same priority.
Same happened here. 4 days later and no notification. It's not like nothing has used Flash in the meantime.

One Drive? Is that one of those "cloud" products that I've been avoiding since they came out? Of course this problem is totally expected.

I live in Oregon. We are very familiar with clouds. They change constantly. Who in his right mind would ever trust his valuable data to a cloud? No one.

If you are a teenager or maybe in your 20s a few years may seem like an eternity, but I'm here to tell you that it's not. Don't trust your data to any medium over which you have no control. You might lose it if you are poor at doing backups on your own, but you will lose it for sure if you trust it to someone else for safekeeping. You will. Not "you might", but you will lose it.

Companies come and go, policies change with management changes, offers and deals change with the economy, and technologies change constantly. Clouds go poof! in the heat of the sun or of the competition or in the fires of corporate hell. I can still print my old B&W negatives. (And I'm not even near to retirement age, yet.) And I still have my own backups of my own data disk with way too much old crap stored there. Maybe losing all of your data once in a while is a small price to pay for a free cleanup. But if you want to keep it, keep it under your own control. Because you are the only one who really cares what happens to it.
